HORSESI-IOE-CALK WRENCH.

Specification of Letters Patent.

Application filed June 9, 1919. Serial No. 302,870.

To all whom it may concern.-

Be it known that I, IIANS P. JononNsnN, a citizen of the United States, residing at Beloit, in the county of Rock and State of Wisconsin, have invented certain new and useful Improvements in HorseshoesCalk renches; and I do declare the following to be full, clear, and exact description of the invention, such as will enable others skilled in the art towhich it appertains to make and use the same.

My invention has for its object to pro vide an extremely simple and inexpensive wrench adapted primarily for attaching and removing horse shoe calks, although it could well be used for other purposes.

With the foregoing in view, the invention resides in the novel device herein described and claimed, reference being made to the accompanying drawing.

figure 1 is a side elevation, partly in section showing the device in use.

Fig. 2 is a plan view.

3 is an edge view.

Fig. 4; is a vertical section on line 4ll of Fig. 2.

In the drmving, the numeral 1 designates a one-piece U-shaped metal bar whose arms 2 are gradually thickened toward their ends, and extended inwardly at said ends to form jaws 3, which are preferably provided with notches l having toothed sides to grip the calk 5. The connecting port-ion G of the bar 1 is thinned and forms a spring to normally spread the arms 2, but if desired, a

.U-shaped spring 7 may rest within the U formed of said bar to increase this action. A 0nep1ece yoke 8 surrounds the free ends of the arms 2 and may be provided at one end with a stud 9 entering a socket 10 in one of said arms, while the other end of the yoke is tapped to receive a screw 11 bearing against the other arm for contracting the U-bar 1 to cause the jaws 3 to grip the calk. The inner end of the screw 11 may well rest in a socket 12 in the arm against which it contacts, while its outer end is by preference provided with a pivoted arm 13 forming a lever for rotating the screw.

The resiliency of the device expands it when the screw is loosened and this action is assisted by spring '7 when it is used, and to retain this spring in place, its ends may well be snugly received in the yoke 8. Tightening of the screw will allow the calk 5 to be tightly gripped for either threading it into the shoe or removing it.

The device is simple and inexpensive, yet is eflicie'nt and in every way desirable, and since excellent results are obtained from the details disclosed, they may well be followed. It is to be understood, however, that within the scope of the invention as claimed, numerous minor changes may well be made.

I claim:

A device of the class described comprising a one-piece U-shaped metal bar having a thinned central portion and gradually thickened toward the ends of its arms, said ends being turned inwardly to provide a pair of jaws, the opposed outer sides of the two arms being provided with shallow sockets near the free ends of said arms, a one piece elongated yoke slidably receiving said arms, a U-shaped spring between said arms having its ends passed through said yoke, the bow of said spring bearing against the corresponding part of the aforesaid bar to retain said spring in place, and. a pair of screws threaded through the opposite ends of said yoke and received at their inner ends in said shallow sockets, one of said screws having a handle for rotating the same to move the two arms inwardl against the resiliency of the aforesaid spring and the thinned portion of the bar from which said arms are formed.

In testimony whereof I have hereunto set my hand.

HANS P. JORGENSEN.
